Overview

The SHTC3-TR-2.5KS is an ultra-low-power digital humidity and temperature sensor specifically designed for mobile and battery-driven applications. It utilizes Sensirion's CMOSens technology to integrate a capacitive humidity sensor and a bandgap temperature sensor on a single chip, providing high reliability and long-term stability in a compact 2mm x 2mm DFN package.

Why Choose This Part

The sensor features an extremely low power profile with a typical sleep current of 0.3 microamps and a measurement current of 0.43mA. It supports I2C Fast Mode Plus and clock stretching, ensuring robust communication and fast wake-up times within 1ms for rapid polling cycles.

Applications

Battery-Powered IoT Nodes
Ideal for remote environmental monitoring where a sleep current of 0.3 microamps and a 1.62V to 3.6V supply range are critical for multi-year battery life.
Consumer Smartphones and Wearables
Small footprint and low power consumption allow for integration into compact mobile devices for ambient weather tracking.
Smart Home HVAC Control
Provides accurate humidity and temperature data via I2C to thermostats and air quality monitors with 16-bit resolution.
